To all whom it may cmwem:

I Be it known that I, O'rrERBEIN K nncor'n a citizen of the United States, resldmg at East Rutherford, in the county of Bergen and State ofNew Jersey, have invented new and useful Improvements in Roofing Materials and Methods of J oimng the Ends of Felt in Making the Same, of WhlCh the following is a specification.

In the manufacture of prepared roofin long sheets of fibrous absorbent matena such as felt, paper, sheets of asbestos and the like, are caused to pass progresswely throu h a waterproofing saturatl compoun held in a suitable tank, then t rough squeeze rolls, frequently through rolls WhlCh apply a skin coating of hard pitch or asphalt, andthen frequently between or under appliances which a ply a coatmg of crushed mineral thereto. t is highly desirable that the sheet shouldbe endless so as not to interru t the operation, particularly as 1t is exceedingly inconvenientto pass the loose front end of the sheet through the various instrumentalities or apparatus referred to. l-leretofore it has been customary to overlap and stitch the rear end of one sheet, when it is nearly exhausted, to the front end of the next sheet. This is a relatively ex nsive operation, and causes much waste an loss of M metlibd and means for joining the two ends of the sheet, and consists in brmgmg the end of the exhausted roll' into roximlty to the end of the new roll, and t en securing the ends of the sheets by means of an adhesive-coated strip of suitable material such as aper, cloth or the like.

n the accompanying drawin Figure 1 shows-my lmprove means for connecting two .felt sheets.

Fig. 2 represents a longitudinal section.

through the same. s

The two sheets are indicated at 5, 6, and they are of such material as is usually employed in the manufacture of prepared roofing sheets, strips or shmgles. The ends of the sheets are placed in a invention comprises a more efi'ective' utting relation,-

they need not necessarilfi be contiguousthough the may be in t 0 same plane .and relatlvelyg ose together. A strip 7, preferably of raft-paper (though linen, tape or other llke material under some circumstances may be used), coated with a suitable ad- Mme m hesive, such as glue or gum, is placed on the adjacent surfaces of the sheets and pressed thereon so as to adhere thereto. The ends of the strip are folded over the side ed s of the sheet and are caused to adhere on t e under surfaces of said sheets.

The connecting stri may be fromthree to six inches wide, an may be drawn from a str1p-severing machine. Hence commerclal gummed paper may be employed for the purposedescribed and rendered adhesive dampening the gum before application. find that this simple means .is effective to Join the ends-of the sheets, and to hold them together when they are passing throu h the various forms of apparatusto'which have herein referred. The connecting ends may be passed between pressing rolls-to insure the adhesion of the connectmg strip thereto. The end of each sheet is covered and held in place by the connecting strip or strips. Usually it.is desirable to loop the fabric prior to its immersion in the saturating tank to.

attempting to set forth all of the forms in which it may be made or all of the modes of 'its use, what I claim is:

1. The herein' described method of joining ,or'connecting'separate elon ated sheets of felt or the like, in the manu acture of roofing material, which consists in bringing the transverse ends of thesheets of felt together .with their side edges in alinement and their ends in abutting relation, and then asting to .and across sald ends a transverse adhesive flexible connecting strig of paper.

2. A continuous r00 ng sheet, comprising two elongated sheets of felt having their on portions adjacent and their side edges in side edges in alinement, and e flexible adhealinexnent, and a, flexible adhesive (gtper sive hinder stri or strips transversely overstrip transversely overlapping said on end lappin said en s, bent around the side edges 10 adhering thereto. thereo and adhering to both faces thereof.

3. A continuous roofing sheet, comprising lln testimony whereof l have afiixed my two elongated sheets of felt having their signature. end portions in abutting relation and their OTTERBEIN KIRAGOFE.
